Application filed. November 12, 1915. Serial No. 61,153.

To all whom it may concern:

Be it known that I, CHRIs'rEN RosrJoRn KADDELAND, a citizen of the United States, residing at Shelton, in the county of Fair.- field and State of Connecticut, have invented a new and useful Improvement in Flat-Bed Printing-Presses; and l do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, 1n y Figure 1 a broken view in side elevation of the front or delivery-end of a fiat-bed printing press constructed in .accordance with my invention. "Fig. 2 a detached reverse plan view of the left hand half of the inking fountain of the press, the guard plate being removed. Fig. 3 a similar view of the right hand half of the inking fountain. Fig. 4: a detached view in left hand side elevation of the inking fountain. Fig.

5 a view of the inking fountain in vertical transverse section on the line ab of Fig. 2. Fig. 6 a detached view in front elevation of the fountain adjusting index.

My invention relates to an improvement in fiat-bed printing presses, the object being to produce a simple, compact, convenient and reliable press, constructed with particular reference to economyof floor space and easy and accurate control of the inking fountain in conformity with the indications of the printed sheets which visualize the distribu tion of the ink at any given time.

A further object of my invention is to pro:

vide dual fountain-adjusting means and an independent self-contained fountain-adjust ing scale. g

With these ends in view, my invention consists in a flat-bed printing press a fountain therefor having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims. In carrying out my invention as herein shown, I employ a vertically movable sheetaccumulating platform or table 2 located below and suspended from a pair of overhanging horizontal arms 3 forming integral parts of the delivery-frame 4:, the said arms or driven from any convenient source of power, the said gears and pinions, with the except on of the Worm-gear 11, being located 1n a gear-casing 18 secured to the column 5 on the left hand side of the press. I

may state, however, i'n-this connection, that I do not llmit myself to the manual or automatic operation of the platform 2, nor to any specific type of mechanism for operating the same whether manually or automatically, or both.

When the platform 2 is in its elevated position, as shown in Fig. 1, ready access may be had under it and between the two columns 5, to the front of the inking apparatus for replenishing and cleaning the same, and for any other attention that it may require. To secure the compactness of form and economy of floor space which are among the objects of my invention, the press is constructed and its parts arranged so that the rear end of the sheet-accumulating platform 2 moves up and down in a vertical path, just clearing the forward end of the inking apparatus which I may here remark may be of any suitable construction as long as it provides for its lateral adjustment from either side of the press without necessitating any access to the interior thereof, aswill be presently described. As herein shown, the said inking apparatus comprises a bowl 19, which is the term commonly applied to its main casting, this bowl being arranged at a right angle to the longitudinal axis of the press-frame 7 and pro-.

the press-frame 7 as shown in F ig. 1. The

inking fountain is provided with a fountain roll 22 having trunnions 23 and driven in .any approved manner in the direction of the arrow 0 in Fig. 5, the means for automatically or manually operating the fountain-roll 22 having nothingto do with my present invention. The said roll 22 rotates in close proximity to the flexible edge of a knife 24 inclined in position and forming the bottom of the ink-reservoir 25, the thickness of the film of ink taken from the reservoir by the periphery of the roll 22 depending at'every point upon the width of the space between the periphery of the said roll and the edge of the said knife.

For adjusting the above described space throughout its length as required to secure a suitable film, I employ a series of correspondingly inclined knife-adjusting screws 26 arranged equidistant from each other and at a right angle to the plane of the knife 24, the lower face of the inner edge of which rests upon the ends of the said screws. Each of the said screws 26 is provided with a spiral pinion 27 engaging with a complementar 29 which corresponds in number to the number of the screws. The said screws 26 are mounted in the bowl 19 while the respective operating-rods 29 are coupled to their complementary screws by means of individual brackets 30. The adjusting-rods 29' of the screws 26, as shown in Figs. 2 and 3, are arranged in two equal groups, the rods of the respective groups being differentiated in length as required to reach their respective screws and all of the 'rods of both groups being provided at their outer ends with square key-shanks 31 each of which has a different number. It is apparent that by turning any rod 29, its complementary screw 26 will be correspondingly moved to increase or decrease its pressure upon that small portion of the edge of the knife with which it is in contact.

It will thus be seen that the edge of the knife 24 is-at all times subject to adjustment, as required, from the outside of the press without any reference to the position of the platform 2, whereby the film of ink supplied by the fountain-roll 22 may beexactly controlled from the sides of the press without entrance thereinto.

For the primary adjustment of the knife 2-1, the screws 26 are furnished at their lower ends with wing-heads 32 by which the edge of the knife 24 is primarily adjusted by the direct manual operation of the screws 26 from the front of the inking fountain when direct access is provided thereto by the elevation of the platform 2. The lateral adjustment of the knife 24, through the rods 29, is designed to provide for such secondary adjustment as may be called for during the operation of the press when it is impossible to get at the screws 26 for operating them directly, due tothe fact that the sheet-accumulating platform 2 then constipinion 28 upon an adjusting-rod.

tutes an obstruction, preventing direct access to the inking fountain.

My improved fountaiii-adjusting means provides for the direct and secondary spotadjustment of the fountain, whereby the adjustment of the fountain may be localized as required, as distinguished from a general adjustment of the fountain throughout its length. This result is accomplished by providing articulate connection between the complementary series of direct and secondary fountain-adjusting means.

To assist the pressman in speedily locating the operating-rod or rods 29 necessary to be operated to thicken or thin the film to correct a defective ink-supply as indicated by the printed sheet, I employ a transversely arranged scale 33 mounted, as shown, upon the tie-rod 3- employed to connect the outer ends of the arms 3 forming parts of the cantaliver-like delivery-frame 4. The respective graduations of the scale 33 are arranged to coincide with the several planes in which the adjusting screws 26 make contact with the flexible edge of the knife 24, so that, in effect, the film of ink is divided into sections subject to localization and individual control. For instance, if the printed sheets 40 as they fall upon the pile on the table 2, show an excess of ink in line with the graduation 9 and a paucity of ink in line with the graduation 20, then the corresponding operating-rods 9 and 20 must be turned from the outside of the press to correct this error. It will be seen that the scale not only localizes the difficulty, but gives it a number by which it may be speedily corrected.

The inking apparatus may be of any approved construction. As shown, it is furnished with a ductor-roll 35 co acting with an ink-bed 36 from which the ink is transferred to the composition rolls 37 which are in contact with the distributing rolls 38.

The platform 2 is shown as provided with feet 39 which permit a truck to be run under it after which it is uncoupled from the cables 8 and replaced by a corresponding platform. As shown the platform is provided with a partial pile of printed sheets 40.

Although I have shown my improved inking apparatus with its dual fountainadjusting means and its independent selfeontained scale in conjunction with a flatbed printing press having a vertically mov-' able sheet-accumulating platform, I would have it understood that I do not so limit the use of my inking fountain,. but hold myself at liberty to adapt it to 'any type of press for which it may be available. I prefer to locate my improved inking apparatus at the front of the press as herein shown, since'in that location its dual-adjusting means and scale are used with the most facility.
